Late Pleistocene – Holocene palaeoenvironmental changes – records from submerged speleothems from the Eastern Adriatic Sea (Croatia)

U-Th and 14C dating, and X-ray diffraction of the parts of submerged speleothems taken from 7 submarine caves and pits on the Eastern Adriatic coast, provided insight to the sea-level fluctuations during the last 220 ka and to the palaeogeographic changes caused by sea-level changes. Oxygen stable isotope ratios were analyzed as palaeoclimate indicators. Due to the climate changes, palaeoenvironmental settings also varied, but not so abrupt and intensive as in the rest of Europe. Namely, owing to the Alps and Dinarides acting as orographic barriers, Eastern Adriatic coast was the border region between periglacial Europe and temperate Mediterranean region. It was, also, refuge area for plant species from the north. Appropriate temperature, humidity and vegetation cover ensured favourable conditions for karstification and speleothems formation processes even during LGM.
